UC1843AMDREPG4 Product Details

UC1843AMDREPG4 Overview


It comes in the 8-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. It is sufficient to generate 1 outputs with this dc motor controller. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 7.6V~30V. Qualified to work in an dc switcher with -55°C~125°C TA. The switching controller can be switched at Up to 500kHz. dc dc regulators can be carried out with Surface Mount. Frequency Control provides dcdc regulator efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a DUAL terminal on the switching converters. Different dc switching's functions can be applied to 8 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. UC1843 can be searched for other relevant dc to dc converter ics. In total, switching converter has 8 pins. Switching converter type is specifically Switching Regulator or Controllers. Statistically, DC regulator outputs 30V volts. This dc to dc regulator accepts only 25V input voltage at most. In most cases, the output current of the dc dc regulator will be 1kA, so note that when you start the project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. 500kHz is the maximum frequency of this dc regulators. With a current supply of 11mA, it runs.
